I bought one for my L3901 a few months ago for my place in AR. I used it for various things around here ( my home place ) including standard limb/tree moving and moving other various things. I have had forks for years but the grapple makes so many things so nuch easier! It was my first grapple, so I cant compare to others but having one beats the heck out of not having one haha. Probably the most impressive thing was clearing brush around an old rotten stump. The huge tree died years ago and I just mowed around the stump. As usual around here, the youpons around it grew bigger and bigger until they were too big to mow after the stump finally mostly rotted away. Of course there were vines mixed in etc. I decided to try the grapple on it and pushed in deep under the roots ( youpons have an extensive root system and cutting the tops doesnt kill them, it can take years to kill them with a chainsaw and mowing ) and closed the lid while pushing. A few good tries and the massive root system came up and I carried it to the pile. A few more passes to get everything, then pulling some dirt in the hole made it all disappear in no time. Ridiculously easy considering it would have taken many hours to do it by hand.
Weekend before last I finally took it to AR. We are having power run to the homesite and the power company let me know the ROW cleared by my dozer guy was too narrow in places. Significantly narrow in some places. We spent 3 days cutting down trees and carrying them to a pile down the hill it ( Catawba 55 ) worked perfectly with the only hiccup being one of the hyd connectors on the 3rd function came unscrewed a little and let the oring poke out which caused a leak. This, of course was unrelated to the grapple. I guess I didnt tighten it up enough when I installed it.
There were a few times that the lid was tweaked while I carried limbs and trees of, obviously, odd sizes, but when I opened it to drop them it sprung right back every time. I may have been putting excess pressure on them, it was hilly and a several hundred yard run to the piles and I didnt want anything shifting, especially since many were on the verge of being too heavy ( btw I found out quickly the shredder on the back wasnt enough ballast when going down hill loaded despite being plenty here on my flat, relatively level home property, duh.. )
Just that one weekend made the grapple worth every penny.
Still not a long term review, but very happy with it so far
